Cartography 2.0 is (was?) an attempt by geographers at Penn State, University of Wisconsin – Madison, and Axis Maps to create an online up-to-date textbook (Creative Commons license) on making modern digital interactive maps. Current chapters online:
- Overview of Animated Maps: Learning from others
- History Of Animated Maps
- Conceptualizing Time, Change and Geographic Process
- Representing Time on Animated Maps
- Representing Time on Static Maps
- Cartographic Text
- Cartographic Interaction: Introduction and Overview
- Multiple, Coordinated Views, Brushing, & Highlighting
- Data Probing and Info Window Design
- Overview: The User Interface
- Interface Evaluation 1: Philosophy
- The Nature of Geospatial Information Uncertainty
Not a how-to guide, more a discussion of history and basic principles, but worth reading just for that. Status is unclear: all of the above chapters are dated September 2009, and while the site states it’s active, there don’t appear to have been any recent additions. I hope it is still active – lots of good stuff just in what’s been posted already.
